Semi-Annual Credit Facility RedeterminationEffective April 2013, the Company and its lending syndicate completed the semi-annual borrowing base redetermination of its revolving credit facility. As a result, Kodiak and its lenders entered into an amendment which increases the Company's borrowing base to $650 million from the previous $450 million. At the present time, the Company elected to limit the aggregate commitment on the revolver to $550 million. Concurrently, the overall facility was increased from $750 million to $1.5 billion with the maturities extended to April 2018. The Company's long-term debt at March 31, 2013 was $1,250 million consisting of $1,150 million in senior notes and $100 million in borrowings under its credit facility. Management believes that the credit facility's undrawn portion, when combined with cash flow from operations, is adequate to fund its anticipated 2013 capital expenditures.

Drilling and Completion Operations UpdateDuring the first quarter of 2013, Kodiak completed 20 gross (14.6 net) operated wells and participated in the completion of 13 gross (3.4 net) non-operated wells. Beginning in March 2013, Kodiak operated with one full-time, 24-hour-per-day completion crew. As drilling operations on several multi-well pads have recently concluded, the Company intends to add a second full-time, 24-hour-per-day completion crew in May 2013. The Company expects to complete 27 gross (23 net) operated wells during the second quarter 2013.

Kodiak's drilling operations continue with seven operated rigs. Currently, four drilling rigs are operating in the Polar project area in southern Williams County, two rigs in the Smokey project area in McKenzie County and one rig operating in Dunn County.

The Company's program to test 12 wells within a 1,280-acre drilling spacing unit (DSU) continues on schedule in the Polar and Smokey operating areas, with two drilling rigs operating in each area. Core data from one of the wells in the Polar project has been obtained and is undergoing evaluation. Completion work on both projects, including a micro seismic program in the Polar area, is scheduled to commence in May 2013.

In an ongoing effort to reduce operating costs, the Company completed the drilling and equipping of three additional water disposal wells during the quarter. The Company anticipates that oil, gas and water lines in the Polar area should be substantially completed during the second quarter of 2013, which would then complete the significant portion of the pipeline work throughout Kodiak's acreage blocks.

Management CommentCommenting on recent developments, Kodiak's Chairman and CEO Lynn Peterson said: "We are pleased with the progress that we achieved during the first quarter and believe that we are on course to deliver sustained production growth during the remaining quarters. The winter we experienced allowed our field operations to move ahead without significant delays. With the onset of the warmer months, we anticipate that our well completions will increase and expect that our efficiencies should improve. Our drilling program continues to see efficiency gains with fewer drilling days which, when combined with better third-party service costs, is helping to drive down our well costs. We look forward to being able to move to the completion procedures on our pilot projects in the coming weeks which should result in continued growth in production, cash flow and reserves for our shareholders."
